Firestop spacers are required at each point where chimney penetrates
a floor space. Their purpose is to establish and maintain required
clearance between chimney and combustible materials. When pipe
passes through a framed opening into a living space above, firestop
must be placed onto ceiling from below as shown in Figure 13.
They also provide complete separation from one floor space to an-
other or attic space as required by most codes. When double wall
pipe passes through a framed opening into an attic space, firestop
must be placed into an attic floor as shown in Figure 14, page 12.
